net: axienet: allow instantiation without a device tree

The ADVA TimeCard X2 is a PCIe timing card driven by ptp_ocp.  Its FPGA
contains an AXI Ethernet MAC with an AXI DMA engine.  The plan discussed
on netdev [1] is for ptp_ocp to register the MAC as a child platform
device described by a software node, so that this driver runs it rather
than a copy in ptp_ocp; Vadim Fedorenko agreed that a platform device is
the way to go.

These two patches are what axienet needs for that, apart from one more
change - letting the DMA device differ from the platform device - which
has no user without ptp_ocp and will be posted together with the ptp_ocp
patches:

1/2 reads the probe-time configuration through the device_property and
    fwnode APIs, so it can come from a software node.  No change for
    device tree users.
2/2 adds a MODULE_ALIAS, so a device registered by name autoloads the
    module.

Both were tested on the X2 with a local ptp_ocp change.
